Pope John XXI

Pope John XXI (Latin:Ioannes XXI; c.1215 – 20 May 1277), born Peter Juliani (Latin:Petrus Iulianus; Portuguese:Pedro Julião), was Pope from 8 September 1276 to his death in 1277. Apart from Damasus I (from Roman Lusitania), he has been the only Portuguese pope. He is usually identified with the logician and herbalist Peter of Spain (Latin:Petrus Hispanus; Portuguese:Pedro Hispano), which would make him the only pope to have been a physician.
